Highreso connected its Takamatsu City Data Center to SINET6, the academic information network run by the National Institute of Informatics, as of September 2026. The access line uses IOWN's All-Photonics Network, from the NTT Group. In a separate detail, the data center in Kagawa Prefecture opened in December 2024 with about 687 square meters of floor area and roughly 10 billion yen invested, operated by Highreso Kagawa.
The Takamatsu City Data Center sits in Kagawa Prefecture and opened in December 2024, built for AI development workloads. The operator, Highreso Kagawa Co., Ltd., reports about 687 square meters of floor area and roughly 10 billion yen invested.
The new connection runs from that data center to SINET6's communication point over IOWN's All-Photonics Network. SINET6 is built and run by the National Institute of Informatics as academic infrastructure. Highreso runs GPU-dedicated data centers at four locations.
